INDIANAPOLIS (AP) — Indiana Gov. Mike Pence praised a ruling by the U.S. Supreme Court striking down President Barack Obama’s executive order on immigration.

Pence said the court’s 4-4 decision Thursday upholds a fundamental constitutional principle dictating that presidents “cannot unilaterally change the law.”

Indiana was one of 26 states challenging the immigration action Obama made after he said Congress wasn’t acting on immigration reform. The move would have prevented deportation for millions of people in the country illegally.

Pence called the executive order an “end run” around the democratic process. He said the proper way to make changes to the country’s immigration laws is passing a bill through Congress.
